About ArrayExpress

What is ArrayExpress?

ArrayExpress is a core EBI database delivered by the Functional Genomics group. The database is a repository for functional genomics data from both microarray and high-throughput sequencing studies, many of which are supported by peer-reviewed publications. Data sets are either submitted directly to ArrayExpress and curated by a team of specialist biological curators, or are imported systematically from the NCBI Gene Expression Omnibus database on a weekly basis. Whichever the source, data are collected in conformity to the "Minimum Information About A Microarray Experiment" (MIAME) and "Minimum Information About a Sequencing Experiment" (MINSEQE) standards.

The team behind ArrayExpress

The ArrayExpress team is part of the Functional Genomics group at EMBL-EBI, led by Alvis Brazma. The team consists of about fifteen bioinformaticians, ontologists, software engineers and web developers, split between the production team led by Robert Petryszak and development team led by Ugis Sarkans. The production team manages, curates and models all incoming data to ArrayExpress, while the development team looks after all the back-end database infrastructure and the public-facing website.
